This is a handy battery charger for the battery of the Sony DSC-RX100. The Sony at the price of the camera contributes no charger is a joke anyway. As to my first major tour (one week after purchasing the camera) I constantly had the problem with the battery charging. On my next trip I wanted to no longer do so and have purchased based on the Rezesionen at Amazon, this charger along with additional battery. The original Sony battery pack costs the way a lot of times the total price of this article. I am highly satisfied with the purchase and would make in return. The only downside to the whole thing: In addition to chargers for mobile phone, tablet and laptop this is the fourth piece in my luggage, and in my backpack it swells of cables and connectors through. For the charger can not. It is a criticism of the manufacturers and their stubborn policy.
